Product Configuration
Refrigeration double defrost heaters typically operate by means of electric heating. Specifically, when current passes through the resistance elements inside the heating tube, the resistance generates heat energy, causing the surface temperature of the heating tube to rise rapidly. Subsequently, this heat is transferred to the surface of the condenser through conduction, effectively melting the frost layer formed due to low-temperature conditions. This process not only restores the heat exchange efficiency of the condenser but also prevents performance degradation or system failures caused by frost accumulation.
The primary function of the double defrost heater tube is to prevent excessive frosting on the surface of cold storage units or refrigeration equipment. Frosting is a common occurrence in low-temperature environments, especially under high humidity conditions, where moisture in the air condenses and freezes on the surface of the condenser. If the frost layer becomes too thick, the double tube defrost heater significantly reduces the heat exchange efficiency of the condenser, thereby affecting the overall performance of the refrigeration system. Therefore, timely removal of the frost layer is crucial for maintaining the normal operation of the equipment.
In addition, the double defrost heater element also has a certain energy-saving effect. By regularly removing the frost layer, it can reduce the increased energy consumption of the refrigeration equipment due to the decrease in heat exchange efficiency, thereby achieving more efficient energy utilization.

Product Customized Design
To meet the demands of various application scenarios, the specifications of double tube defrost heaters can be customized based on actual conditions. For instance, in small household refrigerators, a low-power, small-sized heater may suffice; while in large industrial cold storage facilities, a higher-power, larger-area coverage heating device is required. Additionally, depending on the installation space and usage environment, different shapes of heating tubes (such as straight tubes, U-shaped tubes, etc.) and material types (such as stainless steel, copper, etc.) can be selected to adapt to specific working conditions.
Product Application
Refrigeration defrost heaters are one of the indispensable key components in modern refrigeration equipment and air conditioning systems. Their core function is to provide additional heat to melt the frost formed on the surface of the condenser, thereby ensuring the efficient operation of the entire refrigeration system. In practical applications, this double defrost heater is widely used in cold storage rooms, refrigerators, air conditioners, and other scenarios that require low-temperature environments.
